The detyrosination/retyrosination cycle is the most common post‐translational modification of α‐tubulin. Removal of the conserved C‐terminal tyrosine of α‐tubulin by a still elusive tubulin tyrosine carboxypeptidase (TTC), and religation of this tyrosine by a tubulin tyrosine ligase (TTL) are probably common to all eukaryotes. Interestingly, for plants, the only candidates qualifying as potential TTL

Multiplex and optimization of dCas9‐TV‐mediated gene activation in plants J. Integr. Plant Biol. (IF 4.885) Pub Date : 2020-10-15 Xiangyu Xiong; Jieping Liang; Zhenxiang Li; Ben‐Qiang Gong; Jian‐Feng Li
Synthetic gene activators consisting of nuclease‐dead Cas9 (dCas9) for single‐guide RNA (sgRNA)‐directed promoter binding and a transcriptional activation domain (TAD) represent new tools for gene activation from endogenous genomic locus in basic and applied plant research. However, multiplex gene co‐activation by dCas9‐TADs has not been demonstrated in whole plants. There is also room to optimize

Molecular mechanisms for the photoperiodic regulation of flowering in soybean J. Integr. Plant Biol. (IF 4.885) Pub Date : 2020-10-14 Xiaoya Lin; Baohui Liu; James L. Weller; Jun Abe; Fanjiang Kong
Photoperiodic flowering is one of the most important factors affecting regional adaptation and yield in soybean (Glycine max). Plant adaptation to long‐day conditions at higher latitudes requires early flowering and a reduction or loss of photoperiod sensitivity; adaptation to short‐day conditions at lower latitudes involves delayed flowering, which prolongs vegetative growth for maximum yield potential

Global analysis of CCT family knockout mutants identifies four genes involved in regulating heading date in rice. J. Integr. Plant Biol. (IF 4.885) Pub Date : 2020-09-05 Jia Zhang,Xiaowei Fan,Yong Hu,Xiangchun Zhou,Qin He,Liwen Liang,Yong-Zhong Xing
Many genes encoding CCT domain‐containing proteins regulate flowering time. In rice (Oryza sativa), 41 such genes have been identified, but only a few have been shown to regulate heading date. Here, to test whether and how additional CCT family genes regulate heading date in rice, we classified these genes into five groups based on their diurnal expression patterns. The expression patterns of genes

The Arabidopsi s phosphatase PP2C49 negatively regulates salt tolerance through inhibition of AtHKT1;1. J. Integr. Plant Biol. (IF 4.885) Pub Date : 2020-09-02 Moli Chu,Pengwang Chen,Sufang Meng,Peng Xu,Wenzhi Lan
Type 2C protein phosphatases (PP2Cs) are the largest protein phosphatase family. PP2Cs dephosphorylate substrates for signaling in Arabidopsis, but the functions of most PP2Cs remain unknown. Here, we characterized PP2C49 (AT3G62260, a Group G PP2C), which regulates Na+ distribution under salt stress and is localized to the cytoplasm and nucleus. PP2C49 was highly expressed in root vascular tissues

The Arabidopsis R-SNARE protein YKT61 is essential for gametophyte development. J. Integr. Plant Biol. (IF 4.885) Pub Date : 2020-09-12 Ting Ma,En Li,Lu-Shen Li,Sha Li,Yan Zhang
Gametophyte development is a pre‐requisite for plant reproduction and seed yield; therefore, studies of gametophyte development help us understand fundamental biological questions and have potential applications in agriculture. The biogenesis and dynamics of endomembrane compartments are critical for cell survival, and their regulatory mechanisms are just beginning to be revealed. Here, we report that

Salicylic acid promotes quiescent center cell division through ROS accumulation and down‐regulation of PLT1, PLT2, and WOX5 J. Integr. Plant Biol. (IF 4.885) Pub Date : 2020-10-05 Zhuqing Wang; Duoyan Rong; Dixing Chen; Yang Xiao; Renyi Liu; Shuang Wu; Chizuko Yamamuro
Salicylic acid (SA) plays a crucial role in plant immunity. However, its function in plant development is poorly understood. The quiescent center (QC), which maintains columella stem cells (CSCs) in the root apical meristem and typically exhibits low levels of cell division, is critical for root growth and development. Here, we show that the Arabidopsis thaliana SA overaccumulation mutant constitutively

ABNORMAL SHOOT 6 interacts with KATANIN 1 and SHADE AVOIDANCE 4 to promote cortical microtubule severing and ordering in Arabidopsis. J. Integr. Plant Biol. (IF 4.885) Pub Date : 2020-08-06 Yuanfeng Li,Meng Deng,Haofeng Liu,Yan Li,Yu Chen,Min Jia,Hui Xue,Jingxia Shao,Jun Zhao,Yafei Qi,Lijun An,Fei Yu,Xiayan Liu
Plant interphase cortical microtubules (cMTs) mediate anisotropic cell expansion in response to environmental and developmental cues. In Arabidopsis thaliana, KATANIN 1 (KTN1), the p60 catalytic subunit of the conserved MT‐severing enzyme katanin, is essential for cMT ordering and anisotropic cell expansion. However, the regulation of KTN1‐mediated cMT severing and ordering remains unclear. In this

Arabidopsis E3 ligase KEG associates with and ubiquitinates MKK4 and MKK5 to regulate plant immunity. J. Integr. Plant Biol. (IF 4.885) Pub Date : 2020-09-02 Chenyang Gao,Pengwei Sun,Wei Wang,Dingzhong Tang
Mitogen‐activated protein kinase (MAPK) cascades are highly conserved signaling modules that regulate plant immune responses. The Arabidopsis thaliana Raf‐like MAPK kinase kinase ENHANCED DISEASE RESISTANCE1 (EDR1) is a key negative regulator of plant immunity that affects the protein levels of MKK4 and MKK5, two important MAPK cascade members, but the underlying mechanism is poorly understood. Here

N4-methylcytidine rRNA methylation in chloroplasts is crucial for chloroplast function, development, and abscisic acid response in Arabidopsis. J. Integr. Plant Biol. (IF 4.885) Pub Date : 2020-09-02 Le Nguyen Tieu Ngoc,Su Jung Park,Trinh Thi Huong,Kwang Ho Lee,Hunseung Kang
Although the essential role of messenger RNA methylation in the nucleus is increasingly understood, the nature of ribosomal RNA (rRNA) methyltransferases and the role of rRNA methylation in chloroplasts remain largely unknown. A recent study revealed that CMAL (for Chloroplast mraW‐Like) is a chloroplast‐localized rRNA methyltransferase that is responsible for N4‐methylcytidine (m4C) in 16S chloroplast

Cover Image: ROP2 is sequestered in Sar1DN‐labeled ER‐Golgi vesicles J. Integr. Plant Biol. (IF 4.885) Pub Date : 2020-09-29
ROPs are molecular switches controlling diverse cellular and developmental processes. In this issue, Ge et al. (pp. 1484–1499) report that ROPs are targeted to the plasma membrane not only through the activity of RhoGDIs but also directly by vesicular trafficking, involving COPII, ARF1, AP‐1, and sterols. RhoGDIs and the vesicular trafficking route synergistically mediate ROP targeting and thus cell
